Recently my right click was touchy and didn't want to work on my 5 year old Kensington trackball mouse, and since it was a little dated I figured it was my mouse going out, even though I couldn't get the problem to replicate out of game. So, I dropped 80$ on a newer model Kensington Expert Mouse. Now while in game, my right click and left click will randomly click and attach itself, making either my camera spin or my abilities drag off my bar when I move the cursor. Also, the left click will always show the ripple / click effect on buttons when I click it, but will not always register input and actually use the ability I was clicking on.

I've tried every in game mouse setting combination I could think of. I turned everything off, everything on, all inbetween combinations of mixed mouse settings, and run the game in windowed mode and full screen mode. I'm getting a little irate with the game at this point because it makes my high dps class look like it's standing looking at the butterflies fly by while I'm actually trying to not slam my head against a desk as I spam click my mouse. (I've tried this with both mouses)
